Nevertheless, it is still debated whether patients with KS are exposed to normal androgen levels during fetal life. Anogenital distance (AGD) is an anthropometric measure reflecting androgenization during the fetal period. A shorter AGD in men was associated with infertility, genital anomalies, and testicular cancer. Although other androgen\u2010dependent anthropometric measures such as testicular volume and stretched penile length have been investigated in KS, this is to our knowledge the first study examining AGD in this population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>To investigate the role of AGD as an anthropometric marker of androgenization in adults with KS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We measured AGD, testicular volume, stretched penile length in 50 patients with KS and in 101 Caucasian men with normal total testosterone (tT) levels (&gt;\u00a012\u00a0nmol\/L), using a digital caliper for AGD, an orchidometer for testicular volume and a common meter for stretched penile length.
